Getting Joint Replacement Patients to Actually Do Their Physiotherapy

A knee or hip replacement is, in a real sense, finished the moment I close the incision. What happens for the next twelve weeks — the range-of-motion exercises done daily instead of "when it doesn't hurt too much," the weight-bearing progression followed on schedule instead of by feel — determines whether that surgery actually gives the patient the outcome we operated for. And almost all of it happens somewhere I can't see it.

Patients are handed a physiotherapy sheet at discharge with the best of intentions on both sides. What actually happens after that varies enormously, and we usually only find out how much it varied at the six-week follow-up, by which point a stiff joint from under-doing the exercises, or a swollen one from over-doing them, is a much harder problem to unwind than it would have been in week two.

What tends to go wrong, and when

• Exercises stop when pain starts — the most common failure mode, and the most damaging one, since the discomfort that makes patients stop is often exactly the resistance the exercise is meant to work through.
• Weight-bearing progression drifts — patients either stay overly cautious well past when they should progress, or push ahead of where they are, both of which we'd rather catch at week two than week six.
• Swelling gets normalized — some swelling is expected, but patients often can't tell the difference between expected and concerning without being asked the right comparative question.
• Home exercise frequency quietly drops — from three sessions a day to one, over a couple of weeks, without the patient necessarily registering the decline themselves.

Why a phone call catches this and a leaflet doesn't

The physiotherapy sheet is static — it says the same thing on day one as it does on day thirty, regardless of how the patient is actually doing. A structured follow-up call, at day three, week one, week two and week six, asks something a leaflet can't: how many sessions this week, on a scale of manageable to sharp what does the pain feel like during exercise versus at rest, and how does today's swelling compare to three days ago.

The exercises were never the hard part. Doing them consistently, through the discomfort, on a schedule nobody is enforcing at home — that's the part recovery actually depends on.

For a surgical volume of even a few joint replacements a week, calling every patient through that full follow-up schedule by hand isn't realistic alongside clinic hours and the OR. What's changed for our practice is having those same structured check-ins delivered on schedule to every patient — not replacing the physiotherapist's judgment, but making sure someone is asking the right questions consistently enough to catch a patient who's quietly stopped doing their exercises before it costs them range of motion.

What good compliance follow-up looks like

Any answer that suggests a patient has stopped exercising, is bearing weight incorrectly, or has swelling and pain that's trending the wrong direction gets routed straight to the physiotherapy or surgical team, not left to surface at the next scheduled visit. Most calls are unremarkable — a patient doing fine, logged as such. The value is in catching the ones that aren't, two weeks earlier than we otherwise would have.

Surgery gives a patient the joint. Consistent, well-tracked rehabilitation is what actually gives them the outcome.
